大毘盧遮那成佛經疏 3.18

3.18

經云「復次祕密主！如空中無眾生、無壽命，彼作者不可得。心以迷亂故，而生如是種種妄見」者，《釋論》云「如虛空者，謂但有名而無實法。虛空非可見法，遠視故眼光轉見縹色。諸法亦如是，空無所有，人遠無漏實智慧故棄實相，見彼我男女屋舍城郭等種種雜物，心著如少兒仰視青天謂有實色，有人飛上，極遠而無所見。又如虛空性常清淨，人謂陰曀為不淨。諸法亦如，是性常清淨，婬欲瞋恚等曀故，人謂不淨。」此經云「心迷亂」者，如人以疾病非人等種種因緣，其心迷亂，妄見淨虛空中有種種人物形相，或可怖畏或可貪著。若得本心時，則知此事生時不染虛空、滅時亦非還淨，本來不礙虛空亦不異於空。行者修觀行時，若有種種魔事、種種業煩惱境，皆當安心此喻如淨虛空。雖於無量劫中處於地獄，爾時意無罣礙，如得神通者於空一顯色中自在飛行，不為人法妄想之所塵污也。

The sūtra says: 'Furthermore, Secret Lord, just as in the sky there are no sentient beings, no life-span, and their maker cannot be found, yet because the mind is deluded and confused, such various false views arise,' on which the *Treatise* says: 'Being "like space" means that there is only a name but no real entity. Space is not an object that can be seen; because one looks from afar, the light of the eyes turns back and perceives a pale blue colour. All phenomena are likewise empty and nonexistent. Because people are far from the taintless, real wisdom, they discard dharmatā and perceive varied external things such as "other" and "self", men and women, houses, cities, and walls. Their minds become attached, just as a young child looks up at the blue sky, claiming it has a real colour, whereas if someone flies up extremely far, there is nothing to be seen. Furthermore, just as the nature of space is constantly pure, yet people claim it is impure because of clouds and gloom, all phenomena are also like this: their nature is constantly pure, yet because of the gloom of lust, anger, and so forth, people claim they are impure.' When this sūtra says 'deluded and confused minds', it is like someone who, through various conditions such as illness or non-human beings, has a deluded and confused mind and falsely perceives various forms of figures and things in pure space, which are either terrifying or enticing. When one recovers one's fundamental mind, one realizes that when these things arose they did not defile space, and when they perished they did not restore its purity; originally they did not obstruct space, nor were they different from space. When practitioners cultivate meditative practice, if various demonic events or various realms of karmic afflictions occur, they should all settle their minds in this simile of being like pure space. Even if they abide in hell for immeasurable kalpas, at that time their minds will be free of hindrance, like someone who has attained supernormal powers flying freely within the single manifest colour of space, unsoiled by the dust of false conceptualizations of persons and phenomena.
